Ripple vs Output Current
Note A:
All data in the above graphs has been developed from actual products tested at 25°C. The data is considered typical for the ISR
Note B:
SOA curves represent operating conditions at which internal components are at or below manufacturer’s maximum rated operating temperatures.
